静音です。その為、強風ではない。

案外静音。風力は強くはないが、弱くもない。

Works great, good flow and low noise.

This fan is reasonably quiet and I've used it to replace one of two aging fans in a Kobolt battery charger. The old fan rattled and squeeled as it started up and I didn't want to risk overheating the circuitry so I bought this one as a replacement and it fit perfectly. Very happy to breather new life into an otherwise expensive piece of equipment. Works great, good flow and low noise.
